I recognise your train of thought. :-)

What I think we need to do is scale both the subsurface values and the 
texture, independently but related. (If that makes sense)


   texture {
     pigment { colour}
    finish {
      subsurface { scattering, absorption }* Scale_for_SSLT
      }

scale Scale_for_Texture
    }

PS I notice that you forgot to put your subsurface values in the RC3 
format :-P
